Kone,

Have you tried silver plated copper single strand instead of Litz?  Can
find it cheap sometimes as kynar wire wrap wire.

I like the IRF740 mosfets due to lower gate capacitance, less grunt
needed to gate drive and switch faster.

I have seen the rigid polyurethane foam used for raydomes before but I 
think Styrofoam is polystyrene, probably seen the stuff your talking
about for sound deadening they used in that concrete float though that
looks a lot like the urethane stuff on the domes.  Cool materials you
come up with.

On my rectenna only Schottky diodes worked, regular needed too much
current to perform and ignored the radiant. On the full wave bridge
diodes what HV model do you use?

Found some powder cores to be superior to ferrite as they are almost non
conductive hence much lower eddy losses and heating.  Working on a new
custom core material, maybe when you come back I can send U some.
Materials waiting at house have yet to try, had to split Oregon due to
deadly smoke.

Russian tech superior as they have to be more practical did not have
infinite central banking dollars to waste like US.  Stupid Fed has
changed the gov from for the people to enemy of...  Sad only Ron Paul
could grock this, the rest prefer swilling at the fed trough too much. 
Would be nice if some more moderates could dig it too. Not holding breath.
